Description

Technical Field

[0001] This invention relates to the field of financial equipment technology, and in particular to a banknote reversal method and apparatus based on subsequent reversal. Background Technology

[0002] As the functions of ATMs become increasingly sophisticated, there are further requirements for the immediacy and accuracy of real-time banknote reversal within the channels.

[0003] Currently, existing commutator commutation control methods are all implemented through previous commutation. That is, based on the time required for commutation and the speed of the banknote, the distance between the current banknote and the commutator is calculated to start the commutation, so as to ensure that the banknote has completed the commutation before reaching the commutator, while not affecting the operation of the previous banknote.

[0004] However, when the banknote is tilted at too large an angle, the timing of the reversal is not accurate, which may result in untimely reversal and banknote jamming at the reversing device. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a banknote reversing method and apparatus based on subsequent reversal, so as to quickly and accurately reverse banknotes with excessive tilt angles according to subsequent data.

[0006] In a first aspect, embodiments of the present invention provide a banknote reversing method based on subsequent reversal, applied to financial equipment, the financial equipment including: a reversing device and at least two sensors: sensor A1 and sensor A2; the method includes: S102: determining the theoretical moment T1 at which the reversing device begins reversing based on the distance h between A1 and A2, the time difference t1 between A1 and A2 sensing the current banknote, the channel speed V, and the length L of the current banknote, wherein the foremost edge of the current banknote exceeds a first trigger line by a distance Y, wherein the line connecting A1 and A2 is the first trigger line, and the moment when the current banknote is simultaneously sensed is the theoretical moment T1, the... The preceding banknote is an inclined banknote; S104: Based on the distance Y, the distance Z between the pre-acquired first trigger line and the commutator tooth tip line, and the distance Z1 traveled by the banknote during the commutation process, determine whether the current banknote can be successfully commutated; S106: If the current banknote can be successfully commutated, the commutator performs the commutation at the theoretical time T1; S108: If the current banknote cannot be successfully commutated, the subsequent commutation time T2 is determined based on the positional relationship between the preceding banknote, the interference region, the first trigger line, and the commutator, wherein the preceding banknote is a non-inclined banknote, and the region between the commutator tooth tip line and the commutator central axis is the interference region with a width of C.

[0007] Furthermore, in S102, the process of calculating distance Y is as follows: Formula 1).

[0008] Further, S104 includes: S1042: Multiply the channel speed V by a predetermined reversing time interval t2 to determine the distance Z1 the banknote travels during the successful reversing process, wherein the reversing time interval t2 is the time for the reversing device to complete one reversal; S1044: If Y>Z-Z1, then the current banknote cannot be successfully reversed; otherwise, the current banknote can be successfully reversed.

[0009] Further, S108 includes: S1082: Based on the interference region width C and the distance Z between the first trigger line and the commutator tooth tip, determine the time interval t3 from the arrival of the previous banknote at the first trigger line to its complete departure from the interference region, where t3 = (C + Z) / V; S1084: After the previous banknote arrives at the first trigger line and the time interval t3 has elapsed, the subsequent commutation time T2 is determined.

[0010] Furthermore, the financial device also includes at least two sensors: sensor B1 and sensor B2; S108 can be replaced by: S108': if the current banknote cannot be switched smoothly, the switching time T2' of the current banknote is determined according to the positional relationship between the previous banknote and the second trigger line, the interference area and the switch, wherein the line connecting B1 and B2 is the second trigger line.

[0011] Further, S108' includes: S108'2: Determine the time interval t4 from the front end of the previous banknote reaching the second trigger line to completely leaving the interference area based on the width W of the previous banknote, the distance E between the second trigger line and the central axis of the commutator, and the channel speed V, where t4=(WE) / V; S108'4: The time T2' of the subsequent commutation is when the previous banknote reaches the second trigger line and the time interval t4 has elapsed.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0024] exist Figure 3 In this process, tilted banknotes are transported from left to right. If the existing reversing method is used, when the commutator begins to reverse, the actual angle of the current banknote has already exceeded the distance Y of the first trigger line. At this time, the actual distance X between the current banknote and the tip of the commutator teeth is X. Figure 3 As can be seen, the banknote is already very close to the converter. At this point, switching it again could easily cause the banknote to jam.

[0025] Based on this, this application proposes a banknote reversal method based on subsequent reversal, so as to quickly and accurately reverse banknotes with excessive tilt angles and avoid banknote jamming.

[0026] The banknote reversing method of this embodiment is applied to financial equipment, which includes a commutator and at least two sensors: sensor A1 and sensor A2. The line connecting A1 and A2 is a first trigger line, which is perpendicular to the edge of the channel. The area between the commutator tooth tip line and the commutator central axis is an interference region with a width of C. The existing reversing mechanism is that when both A1 and A2 sense the passage of a banknote, the reversing mechanism is triggered, and the commutator begins to reverse, at which point the theoretical time T1 is reached.

[0027] In this embodiment, the "previous banknote" is a normal banknote that is basically not tilted, and the "current banknote" is a banknote with a larger tilt angle.

[0028] S102: Based on the channel speed V, the current banknote length L, the distance h between sensor A1 and sensor A2, and the time difference t1 between sensor A1 and sensor A2 sensing the current banknote, determine the theoretical moment T1 when the commutator starts to switch directions, and the distance Y that the front end of the current banknote exceeds the first trigger line.

[0029] Specifically,

[0030] The calculation formula is as follows: Formula 1).

[0031] S104: Based on the distance Y, the distance Z between the first trigger line and the commutator tooth tip line obtained in advance, and the banknote running distance Z1 during the commutation process, determine whether the current banknote can be successfully commutated.

[0032] Step 2-1: Determine the distance Z1 that the banknote travels during the successful reversal process based on the pre-acquired channel speed V and the pre-determined reversal time interval t2, where Z1 = t2 * V.

[0033] Among them, the channel speed V is generally 1.25m / s, 1.6m / s, 1.8m / s, 2m / s, and is determined according to the actual situation; t2 is the time interval for the commutator to complete one commutation. Considering the actual commutation error, t2 should be slightly longer than the actual commutation time required.

[0034] Step 2-2: If Y > Z-Z1, it means that the current banknote cannot start the previous reversal in time, otherwise the banknote will be jammed; if Y ≤ Z-Z1, the banknote will not be jammed during normal reversal (normal reversal means starting the reversal at time T1).

[0035] S108, determine the reversal time T2 of the current banknote based on the distance Z between the previous banknote and the interference area, the first trigger line and the commutator tooth tip line.

[0036] First, calculate the time interval t3 from when the previous banknote arrives at sensor A1 and sensor A2 (since the previous banknote is tilted by default, the arrival time at the two sensors is the same, i.e., when it arrives at the first trigger line) until it completely leaves the interference region, where t3 = (C + Z) / V; where C is the width of the interference region.

[0037] When the previous banknote reaches the sensor A trigger line (i.e., the first trigger line) and after a time interval t3 (i.e., the reversing time T2), the reversing device is activated to perform the reversing action, thus successfully completing the reversing action of the current banknote.

[0038] This embodiment only requires physical quantities such as sensors A1 and A2, commutator, current banknote and previous banknote. The commutation time can be determined by the latter data, thus avoiding banknote jamming. Example

[0039] In this embodiment, the "previous banknote" is a normal banknote that is basically not tilted, and the "current banknote" is a banknote with a larger tilt angle. In addition to sensors A1 and A2, the financial device in this embodiment also needs to include sensors B (sensor B1 and sensor B2), and the line connecting B1 and B2 is the second trigger line; the second trigger line is perpendicular to the channel edge. This embodiment relies on sensors B1 and B2; without these two sensors B, this embodiment cannot be executed.

[0040] In Example 1, S108 can be replaced by S108': Based on the positional relationship between the previous banknote, the second trigger line, the interference area, and the commutator, the commutation time T2' of the current banknote is determined, as shown in the flowchart. Figure 2 As shown.

[0041] To avoid banknote jamming, the tail of the previous banknote must leave the interference area of ​​the converter before the current banknote can be reversed.

[0042] like Figure 3 and Figure 4 As shown, when the front end of the previous banknote reaches the second trigger line, the entire previous banknote has not yet left the interference area. The time from when the front end of the previous banknote reaches the second trigger line to when the previous banknote completely leaves the interference area is t4, where t4 = (WE) / V; W is the width of the previous banknote, and E is the distance from the right edge of the interference area (i.e., the central axis of the commutator) to the second trigger line.

[0043] Therefore, when the current banknote (here, the previous banknote must be an untilted banknote) reaches the second trigger line and is blocked for time t4, the reversing moment T2' of the current banknote is reached, and the reversing device is activated at this time.

[0044] This embodiment uses physical quantities such as sensors A1, A2, B1, B2, commutator, current banknote and previous banknote, and the subsequent data to determine the commutation time, thus avoiding banknote jamming. Example

[0045] This invention provides a banknote reversing device based on subsequent reversal, comprising:

[0046] The distance Y calculation module is used to determine the theoretical moment T1 when the commutator starts to switch directions based on the distance h between A1 and A2, the time difference t1 when A1 and A2 sense the current banknote, the channel speed V, and the length L of the current banknote. The distance Y of the front end of the current banknote exceeds the first trigger line is defined as follows: the line connecting A1 and A2 is the first trigger line; the moment when the current banknote is sensed is the theoretical moment T1; and the current banknote is a tilted banknote.

[0047] The judgment module is used to determine whether the current banknote can be successfully reversed based on the distance Y, the distance Z between the pre-acquired first trigger line and the commutator tooth tip line, and the distance Z1 that the banknote travels during the reversing process.

[0048] The first commutation module is used to perform commutation at the theoretical time T1 if the current banknote can be successfully commutated.

[0049] The second reversing module is used to determine the reversing time T2 of the next item based on the positional relationship between the previous item, the interference area, the first trigger line and the reversing device if the current banknote cannot be reversed smoothly. The previous item is a non-tilted banknote, and the area between the reversing device tooth tip line and the central axis of the reversing device is the interference area with a width of C.

For the sake of brevity, any parts not mentioned in the device embodiment can be referred to the corresponding content in the aforementioned method embodiment.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
